Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. When the highest degree of the polynomial is 3, i.e. Make your child a Math Thinker, the Cuemath way. If alpha, beta and gamma are the zeros of the polynomial then the roots of the polynomial will be (x-alpha) (x-beta) and (x-gamma). Thus, p(x)= k (x-alpha) (x-beta) (x-gamma), where k is any constant • Multiply out $(x - \alpha) (x - \beta) (x - \gamma)$ to se how. Sum of the zeros = 4 + 6 = 10 Product of the zeros = 4 × 6 = 24 Hence the polynomial formed = x 2 – (sum of zeros) x + Product of zeros = x 2 – 10x + 24.
